IMPROVEMENT IN SUGAR-MILLS.

Specification forming part of Letters Patent No. 24,697, dated July 5, 1859.

To all whom it mayconcern:

Be it known that I, JosErH R. GATES, of Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Sugar-Mills, of which the following is a full and exact description, reference being had to the accompanying drawings and the letters marked thereon.

Figure 1 is a perspective, and Fig. 2 a sectional viewshowing the construction and general arrangement of the machine.

A is a lever designed to operate the wheel B, which gears with the wheel O, operating the crushing-rollers H H, which are caused to operate together by the gearing F F. The wheel D is upon the same shaft with the roller II and beveled wheel 0, and gears with the wheels E E, which are upon the same shaft with and operate the grooved friction-stripper G G G G, which are composed of indiarubber, with a groove out in the periphery; and, being arranged opposite each other, an aperture is formed between the same, through which the cane passes to the rollers H H. The rollers G G G G are also notched at the sides of the grooves, or cross-grooved, for the purpose of increasing their elasticity and stripping-power.

K K are lever-bearings for the lower roller, H, and, being fulcrumed at M M, are operated by the set-screws I I and springs J J, upon which they rest. The tenons IT N serve as guides, and slide in grooves or slots in the frame of the machine.

L L are troughs designed to receive the j nice I as it runs from the crushing-rollers II H.

The following is the operation of the mill: The cane is fed into the rollers between the strippers G G G G, which are rapidly revolved outward upon the same by the gearing E E, and by which the leaves are stripped. The elastic grooves of the strippers G G G G fit closely upon the small stalks, producing friction sufficient to strip the leaves from the same, while their grooved form and elasticity allow the largest stalks to pass through between them. The rollers H H may be kept in close contact by the setscrews I I, while the springs J J allow sufficient elasticity to prevent any solid substance from breaking the rollers as it passes between them.

What I claim, and desire to secure by Letters Patent, is-

The grooved frictiou-rollers G G G G, when used for stripping the blade from the stalk,

substantially as set forth.
